Abstract
A process is disclosed for producing doped tungsten wire having a combination of relatively low strength and high ductility. The process involves swaging recrystallized rod to a diameter of from about 80 to about 125 mil, drawing this rod into wire having a diameter of from about 52 to about 62 mil, and stress-relief annealing the wire to impart the combination of low strength and high ductility to the wire when it is drawn to about 35 to about 37 mils.
